1.73 Q740 intel i7
nvidia gt435M 2gb gpu
6gb RAM
7200 rpm hdd

i run it in high settins and its a bit laggy and its not smooth, do you think that a futher gpu driver update will increase performance? do dx11 help? and please dont ask me to change the gpu, its a laptop. just tell me that if you think that it will improve performance and/or release lower graphics, or it will not?
